The Sliding Mode Controller Design of Half Bridge Bidirectional DC-DC Converter having Constant Power Load for Electric Vehicles

Nowadays, power converters with their controllers are

widely used in several systems to achieve the desired outputs.

Therefore, this paper presents the sliding mode controller

design of half bridge bidirectional DC-DC converter having

constant power load for electric vehicle to regulate the system

DC bus voltage. The controller parameters design is based on a

trial and error method. The intensive time-domain simulation

using SimPowerSystemTM on SIMULINK/MATLAB is used to

examine the controller performances. The results show that the

proposed sliding mode controller can regulate the DC bus

voltage to be a constant even the constant power loads of the

system are changed. In addition, the good controller

performances in terms of rise time, settling time, and percent

overshoot can be achieved.
